We present data from small angle neutron scattering (SANS) on the polyelectrolyte side chain liquid crystalline phases of porcine stomach mucin. There is a polydomain nematic phase at concentrations above point brush overlap. Also, proteoglycans were seen to orient under influence magnetic field below which brushes do not extensively The can be used investigate nature entanglement coupling between molecules. structure factor peak scales as c1/3 across complete concentration range, implying liquidlike behavior (0.4−680 mg/mL). rheological evidence for shear thinning with four regimes: dilute, semidilute, entangled crystalline, and crystalline. length cross-sectional radius polymeric could measured SANS. Static light SANS provide changes in osmotic compressibility phases.
